COTTON-SEED LINTER.

SPECIFICATION forming part of Letters Patent No. 321,824, dated July 7, 1885.

Application filed March 9, 1885. (No model.)

To all whom it may concern:

Be it known that we, JULIUS J. KOCH and VALTER P. GRATH, both of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in GottonSeed Linters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a transverse section through the machine. Fig. 2 is an enlarged detailsection of the toothed cylinder at 2 2, Fig. 4, part of a basket being also shown. Fig. 3 is a front View of one of the slotted baskets which 0011- [5 tain the cotton-seed. Fig. 4 is an enlarged detail section'at 4. 4, Fig. 1. Figs. 5, 6, and 7 are detail front views, showing portions of toothed ribs with teeth of different constructions. Fig. 8 is a section at 8 8, Fig. 5.

A is a box which receives the lint which is scraped from the seeds within the baskets B, and carried out by the teeth of the cylinder Oh The baskets are made of. sheet metal, preferably bent into the form shown, so that as the mass of cottonseed is engaged by the teeth (I, which work through the slots b of the baskets, the mass may be caused to revolve in the baskets, thus presenting fresh portions to the teeth, the rounded shape of the baskets 0 at b conducing to the rolling of the mass. The baskets are secured to the sides of the box A by screw-bolts E, and each is formed on its side, contiguous to the cylinder, with a concavity which is preferably concentric with the said cylinder. The toothed cylinder 0 is constructed as follows: c is a cylinder, which may be of wood,

and through which passes axially a shaft, F,

upon which is fixed a drive pulley or wheel.

(Not shown.) The cylinder has at its ends two similar heads, 0, which are secured to the shaft F by keys or otherwise, and which are connected together and to the core-cylinder c by long bolts 0. The heads 0 have marginal 5 inturned flanges cflbetween which and the circumference of the core-cylinder are annular recesses. In these annular recesses, at the ends of the cylinder fit the lugs d of an annular series of serrated strips, D, that form the surface of the cylinder between the two flanges 0 The teeth (2 of the strips of metal D, have one side, (1 in the plane with the front side of the strip, and the rear sides, d of the teeth are beveled, so that the teeth have a chisel-edge that may be a plain edge. as shown in Figs. 4 and 5, serrated, as in Fig. 6, or corrugated, as in Fig. 7. The sides (I of the teeth may be at'right angles to the strip D, or may have an equal bevel, as shown in Figs. 4 and 7, or one side, (1*, may be perpendicular and the other beveled, as shown in Figs. 5 and 6. The tooth-strips D are so shaped that their sides fitltightly together, so as to form practically a solid layer, as seen in Fig. 2, the strips being firmly held in position by the flanges c of the heads.

In working themachine the cotton-seed is fed into one end of the baskets and the linted cotton-seed escapes from the other end of the baskets, the lint being scraped from the seeds and carried through the slots into the lint-box A by the revolving teeth. This movement of the cotton-seed through the basket is 13.5 to the fact that the fresh material is being constantly fed in at one end of said basket while the other is left entirely open. Hence no matter how slight the pressure at the receiving end may be, as the material will inevitably move in the direction of the lesser resist ance, it follows that it will move toward the delivery end as it is revolved by the action of the cylinder.

Two baskets are shown, but a single one only may be used if preferred, or more than two may be used.

If desired, a cleaning brush or brushes may be used to discharge the lint from the teeth, said brush or brushes being arranged in the same/manner as the saw' cleaning or clearing brush of a cotton-gin.

We are aware that a cylinder having beveled or chisel-shaped teeth is not new, and do not claim such, broadly, as our invention.

WVe claim- 1. A basket, composedof sheet metal, having a concavity bent into the side thereof and slots cut through it at said concave portion, substantially as and for the purpose set forth.

2. The combination, with a basket having a concavity in the side thereof and slots cut through it at said concave portion, of a cylinder having teeth adapted to work in said slots, as set forth.

3. The combination, in a linting-machine,

Too

of a cylinder having teeth arranged thereon, and a basket having slots in which said teeth work, and rounded parts I), substantially as and for the purpose set forth.

4. The combination, in a 1inting1nachine, of a toothed cylinder, a basket having slots through which said teeth project, and a rounded part, b, on the side to which the material is carried by the action of the teeth, substantially as set forth.
